Left femoral upper shaft medial subcortical marrow edema signal with subtle small transversely oriented stress fracture line. Mild peri osseous soft tissue edema.
Findings are impressive of left femoral upper shaft medial stress fracture.

On PET-CT, the lesion shows mild increased FDG uptake with SUV max 2.4 with mild cortical thickening/sclerosis.
Case Discussion
MRI features of a stress fracture include periosteal reaction, endosteal bone marrow edema, and a linear osseous discontinuity.
On PET-CT, It usually shows mild increased FDG uptake.
